Daathos · Architecture
Systems that endure
time and
scale.
Architecture is not documentation: it is the set of decisions that shape what can and cannot be done in the future. Every choice has a cost, and that cost must be explicit.
C4 model
Visualize in three
levels of detail.
The C4 model organizes architecture in progressive layers. Click each level to explore.
Principles
The convictions behind
every technical decision.
Context before solution
No architectural decision is made before understanding the business domain, real constraints, and the team that will operate the system. Architecture without context is theory.
Incremental evolution
Large systems emerge from small systems that work. Each sprint ships something production-ready. We avoid big-bang rewrites; we use strangler fig and seams.
Explicit, traceable decisions
Every architectural trade-off is documented in an ADR. The future team does not need to guess why something was done: the reason is recorded.
Operability as a requirement
Structured logs, metrics, distributed traces, and runbooks are part of the system, not bolted on later. A system no one can operate is a system that will fail in production.
Loose coupling, high cohesion
Components should know as little as possible about each other. Clear interfaces, versioned contracts, asynchronous communication where it fits. Change in one place does not break another.
Security by design
Authentication, authorization, audit, and encryption are designed into the architecture, not patched in. Threat modeling before the first line of code.
Architecture Decision Records
Decisions recorded,
reasons preserved.
Full ADRs are available in the project private repository after engagement begins.
